Answer:
cells
Step-by-step explanation:
Let the number of cells she used in 2nd experiment be "x"
Since the latter experiment she uses LESS, we can say:
"<em>What number times 2000 gives us 2.8 * 10 ^ 12??"</em>
<em />
We can create an equation such as:
Thus, x would be:
Let's convert 2000 into scientific notation first. We would take decimal point to the left until we have 1 digit to left of decimal and make 10 raised to that many units we take left "to the power".
So
2000 = 2 * 10 ^3
Now, let's remember rule of dividing numbers in scientific notation:
Now, we do our problem using this rule:
Thus, she used cells in her 2nd experiment
Answer:
The answer is 5 dude.
Step-by-step explanation:
You cannot multiply 3 to get fifty
A common form of a line equation is:
y=mx + b , where m is the slope. If two lines are parallel they have equal slopes. So first step is to transform these equations to common form:
A) y=-3x+2
B) x-3y =-3
-3 y =- x-3 / :(-3)
y = 1/3 x +1, 1/3 ≠ -3
C) 3x + y = -6
y = -3x - 6
D) 6x + 2 y = 2
2y= - 6x+2 /:2
y = -3x +1
